Macadamia tree takes five to twelve years to produce nuts and a good tree can produce nuts for 40 years. The trees require a hot subtropical climate without much humidity. Macadamias are now widely used in the confectionery, baking, ice cream and snack food industries.
Macadamia nuts have a sweet taste and are a super source of energy. They also contain large amounts of vitamin A and iron, as well as zinc and calcium.
Raw macadamias have been awarded the South African heart mark as an approved part of the Heart and Stroke Foundation healthy eating plan. They can be eaten raw or roasted.
